A fault in the voltage-control mechanism may thus cause a battery to become overcharged, which, in turn, might precipitate a deeper discharge than normal.
电压控制的装置出现错误可能会导致蓄电池组充电过度，这反过来可能会加速放电，比正常情况更严重。

It has excellent output stability by following up the variation of input voltage and connected load, they almost can't be damaged in normal use.
